TECHNICAL FIELD

The embodiments of the present disclosure relate to the field of augmented reality, and in particular to an augmented reality system that supports customized multi-channel interaction.

BACKGROUND ART

AR (Augmented Reality) technology is a novel human-computer interaction technology that can add virtual information to the real world, thereby skillfully fusing virtual information with the real world, i.e., “augmenting” the real world.

Existing AR display technology devices mainly include an AR head-mounted device. The AR head-mounted device integrates the display unit into a head-mounted device, using a near-eye display technology. Although the above device achieves the integration of components, it increases the weight of the head-mounted device. Therefore, when the user experiences the device, it is often too heavy that dampens the user's experience.

In addition, the use of the near-eye display technology usually limits the viewing angle of the lens, which will also dampen the user's experience.

Accordingly, this field needs a new augmented reality system to solve the above problem.

Hereinafter, the present disclosure will be described in detail with reference to the drawings and in conjunction with embodiments.

Firstly refer to FIG. 1. FIG. 1 is a schematic diagram of some structures of an augmented reality system supporting customized multi-channel interaction according to the present disclosure. As shown in FIG. 1, the head-mounted sensor assembly 1 is used to capture the user's multi-channel interactive input information, and transmit the collected interactive input information to the computing device 2. The computing device 2 generates or modifies the display content of augmented reality according to the aforementioned interactive input information, and transmits it to the display module 5. The display module 5 superimposes and displays the background content and the computed augmented reality display content. It should be noted that, different from displaying onto the head-mounted display device in the prior art, the above display module and head-mounted sensor are set to the far end at intervals. For example, the display module 5 may be a computer monitor, a plasma display screen, a liquid crystal display screen, and so on. Those skilled in the art can make a selection according to the actual situation. No limitation is made here.

To be specific, the aforementioned background content may be an image or video displayed in the display module 5. It can also be a virtual dynamic or static scene generated by conventional technical means. Taking the generation of a dynamic scene as an example, first, the elements of this dynamic scene may be determined, namely the target, background, and target movement and the like. Next, the path and angle of movement of the target and so on are determined. In the end, the required dynamic scene image is generated. Those skilled in the art can generate the aforementioned virtual dynamic scene or static scene according to the prior art or conventional technical means.

The above augmented reality display content may include images or videos, generated virtual dynamic or static scenes or objects, and visualization effects of interactive operations. The interactive operations may be human-computer interactive operations performed by the user with the system through the head-mounted sensor. Specifically, the interactive operations may include at least one of the following: gesture interactive operation, voice interactive operation, and eye movement interactive operation. In order to complete the above operations, relevant sensors can be provided on the head-mounted sensor assembly to collect information. The sensor assembly may include a camera, a microphone, a gesture sensor, and an eye movement tracking sensor. The user's interactive input information is acquired through the above-mentioned sensors.

Further, the corresponding visualization effects can be presented through the above interactive operations. For example, when a gesture sensor is used, through the acquired user's gesture interactive input information, the effect of the hand moving an object in the augmented reality display content can be simulated and etc.

In response to receiving the aforementioned interactive input information, the computing device implements the corresponding interactive operations. In other words, the augmented reality display content can be modified in real time by the computing device through interactive operations, and only the part of it within the augmented reality window is displayed. In this way, the function of the computing device generating or modifying the content of the augmented reality is realized. Those skilled in the art can choose among existing related sensors to implement the above interactive operations by conventional technical measures.

Next, the system will be described with reference to FIG. 1 and FIG. 2. FIG. 2 is a schematic diagram of some further structures of an augmented reality system supporting customized multi-channel interaction according to the present disclosure. As shown in FIG. 1 and FIG. 2, the augmented reality system further comprises an augmented reality window 3 displayed to the display module 5. The augmented reality window 3 is used to display the display content of the augmented reality. To be specific, the shape and size of the augmented reality window 3 can be set by users themselves or the system defaults. To be specific, the user inputs the shape and size of the augmented reality window 3 through a human-computer interactive operation interface. The shape can be round, rectangular, etc. The size may be the side length of the above shape, the center of a circle, and so on.

Further, the augmented reality window 3 may be back-projected to the near-eye end of the user to form a virtual window 4. The shape of the virtual window 4 is the same as the shape of the augmented reality window 3. The distance between the virtual window 4 and the user affects the size of the augmented reality window 3. That is, when the virtual window 4 is close to the user, the size of the augmented reality window 3 presented to the display module 5 becomes larger. Therefore, without the user moving, the size of the augmented reality window 3 can be adjusted by adjusting the distance between the virtual window 4 and the user.

The position where the augmented reality window 3 is displayed to the display module 5 is determined through the following steps:

The first step is to establish a coordinate system according to the display range of the display module 5.

In some embodiments, a point can be selected in the display range of the display module 5 as the origin of coordinates. Further, a three-axis coordinate system is established on the basis of the origin. As an example, the upper left corner of the display range of the display module 5 may be determined as the origin of coordinates, and the length direction may be the X-axis, the height direction is taken as the Y axis, the vertical direction between the user and the display module 5 is the Z axis, thereby forming a three-axis coordinate system.

The second step is to determine according to the following formula the point coordinates of the point on the boundary line where the virtual window 4 is projected to the display module 5:

PA _(i)=λ_(i) PP _(i);

Wherein P represents the coordinates of the center point of the two eyes, wherein the coordinates of the point P can be determined through related algorithms. For example, the PNP (Perspective-n-Point) algorithm or the EPNP (Efficient Perspective-n-Point) algorithm can obtain the center point coordinates of the two eyes through key point detection, coordinate system conversion, and so on.

P_(i) represents the coordinates of the i^(th) point on the edge of the virtual window 4, wherein the size of the augmented reality window 3 can be adjusted by adjusting the distance between the virtual window 4 and the user without the user moving. When determining the size of the augmented reality window, the distance from the virtual window 4 to the user is known. In turn, the coordinates of the i^(th) point on the edge of the virtual window 4 can be determined through the size, shape, and P point coordinates of the virtual window 4.

A_(i) represents the point coordinates of the point where the straight line formed by starting from point P as the origin and passing through point P_(i) intersects the display module 5;

PA_(i) represents the distance from point P to A_(i);

PP_(i) represents the distance from point P to P_(i), wherein the value of PP_(i) can be determined through the coordinates of point P and the coordinates of point P_(i);

λ_(i) represents the quotient of PA_(i) and PP_(i), and λ_(i) is determined by the Z-axis coordinates of the three points P, A_(i), and P_(i). To be specific, the distance from the virtual window 4 to the user is known, and the distance from the display module to the user can be determined through the coordinates of point P.

The value of PA_(i) can be calculated by the above formula. Since the point A_(i) is presented on the display module 5, the coordinates of point A_(i) can be determined according to the value of PA_(i).

In the end, the point coordinates of multiple points on the above-mentioned boundary can determine the display range of the augmented reality window and the display position on the display module.

Further, the computing device may determine the object in the display content that the user's eyeballs are focusing on by using the following formula:

λ₁*λ₂*λ₃>0;

Wherein λ₁ is determined by the following formula:

$\lambda_{1} = \left\{ {\begin{matrix} {1,\ {{\left( {x - x_{r}} \right)^{2} + \left( {y - y_{r}} \right)^{2} + \left( {z - z_{r}} \right)^{2}} \leq r^{2}}} \\ {0,\ {{\left( {x - x_{r}} \right)^{2} + \left( {y - y_{r}} \right)^{2} + \left( {z - z_{r}} \right)^{2}} \geq r^{2}}} \end{matrix};} \right.$

Wherein (x, y, z) are the coordinates of the object in the display content, wherein the coordinates of the display content object can be determined in a variety of ways, for example, the coordinates can be determined by a target detection algorithm or a related spatial coordinate algorithm. In addition, the technician can also preset the coordinates of the object in advance.

(x_(r), y_(r), z_(r)) are the three-dimensional focus point coordinates of the left and right eye sight direction, where the three-dimensional focus point coordinates can be determined by the existing tracking sensors.

r represents the attention radius; wherein the spherical range formed by the attention radius represents the preset range of the focus point, wherein the above attention radius may be determined by a technician through a lot of experiments. It can also be set by the computing device by default.

In response to λ₁=1, it indicates that the object is in the preset range of the focus point.

In response to λ₁=0, it indicates that the object is out of the preset range of the focus point.

Wherein λ₂ is determined through the following formula:

$\lambda_{2} = \left\{ {\begin{matrix} {1,\ {t \geq t_{d}}} \\ {0,\ {t < t_{d}}} \end{matrix};} \right.$

Wherein t represents the time that the focus point continuously selects the object within the preset time period, which may be that the focus point overlaps the display range of the object, t_(d) is the preset threshold of the time, wherein the preset time and the preset threshold can be determined by a technician through a large number of experiments, or set by the computing device by default.

In response to λ₂=1, it indicates that the time the object has been focused on exceeds a preset threshold;

In response to λ₂=0, it indicates that the time the object has been focused on is less than a preset threshold;

Wherein the specific formula of λ₃ is as follows:

$\lambda_{3} = \left\{ {\begin{matrix} {1,\ {x_{\min} \leq x \leq {x_{\max}\ {and}\mspace{14mu} y_{\min}} \leq y \leq y_{\max}}} \\ {0,\ {x_{\min} > {x\ {or}\mspace{14mu} x} > {x_{\max}\ {or}\mspace{14mu} y_{\min}} > {y\ {or}\mspace{14mu} y} > y_{\max}}} \end{matrix};} \right.$

Wherein (x_(min), x_(max)) represents the minimum and maximum values of the augmented reality display window in the x-axis direction, (y_(min), y_(max)) represents the minimum and maximum values of the augmented reality display window in the y-axis direction;

λ₃=1 means that the object is inside the augmented reality display window;

λ₃=0 means that the object is outside the augmented reality display window.

Furthermore, in response to when the number of objects in the display content that the eyeballs have focused on is multiple, the computing device determines through the following steps the order in which the multiple objects are displayed:

For the determined objects that the eyeballs have focused on, the probability of each object being displayed is determined by the following formula:

${P_{i} = {1 - {\min\;\left( {1,\frac{d_{i}}{r}} \right)}}};$

Wherein P_(i) represents the probability of the i^(th) object being displayed;

d_(i) represents the distance between the i^(th) object and the gaze point; and

The object to be displayed first is determined according to the probability of each of the objects being displayed.

In some modes of implementation of certain optional embodiments, responsive to the display module displaying a plurality of augmented reality windows, and the object of the display content being in the range of the plurality of augmented reality windows or the object being selected by a plurality of the interactive operations, the computing device displays one by one the objects modified by each of the interactive operations, and displays them in each of the aforementioned augmented reality windows. Next, description will be made in combination with FIG. 3. FIG. 3 is an application scenario diagram of an augmented reality system supporting customized multi-channel interaction used by more than one person according to the present disclosure. When the display module shows two augmented reality windows (31 and 32 in the figure). When the display content of each of the above augmented reality windows comprises the same object 6, and when the object 6 is selected or modified by the user's interactive operation, the scenes when the above interactive operations change the object 6 can be displayed in sequence according to the set factors. The above-mentioned set factors may be the time when the user's interactive operations occur, or may be a sequence set for different users in advance.

In the augmented reality system disclosed in some embodiments of the present disclosure, the virtual window formed by back-projection of the augmented reality window can adjust the size of the augmented reality window by adjusting the distance between the virtual window and the user. In this way, the user can customize the size of the augmented reality window to improve the user's experience.

In addition, as the user's perspective changes, the position of the augmented reality window displayed at the display module may change. By constructing a three-axis coordinate system on the display module, and at the same time, based on the coordinates of the virtual window and the user, the position of the point of the augmented reality window edge on the display module can be accurately determined, thereby determining the position of the augmented reality window in the display module. Therefore, a reasonable position of the augmented reality window on the display module is displayed according to the change of the user's perspective, which can more vividly and appropriately display the content of augmented reality, thus improving the user's experience.

Besides, the object in the display content that the user's eyes have focused on is determined by determining the preset range of the user's focus point, the time of the object being focused on, and whether the object is within the range of the augmented reality display window. In this way, the object which the user has focused on can be accurately determined, and thereby displayed precisely, thus improving the accuracy of the system as well as the user's experience.
